Answer:
Step-by-step explanation:
perpendicular is 90 degrees or inverse slope of that point
y = -1/4x -1
so the inverse slope of -1/4 is 4
now the other equation is
y = 4x - 1
So the two equations are
y = -1/4x -1
y = 4x - 1
Answer:
it's D
Step-by-step explanation:
Answer: 20y - 7.5
(3 - 8y) * (-2.5)
(3 * -2.5) + (-8y * -2.5)
-7.5 + 20y
20y - 7.5
